Network Address

Translation

With the NAT, you can translate an Internet protocol address

used within one network (for example a private IP address used

in a local network) to a different IP address known within

another network (for example a public IP address used on the

Internet).

Choose None to disable NAT.

Choose SUA Only if you have a single public IP address. SUA

(Single User Account) is a subset of NAT that supports two

types of mapping: Many-to-One and Server.

Choose Full Feature if you have multiple public IP addresses.

Full Feature mapping types include: One-to-One,

Many-to-One (SUA/PAT), Many-to-Many Overload, Many-

One-to-One and Server. When you select Full Feature you

must configure at least one address mapping set!

See Chapter 9, “Network Address Translation (NAT),” on page

107 for a more detailed discussion on the Network Address

Translation feature.

Note: The Business Secure Router supports only one PPTP server

connection at any given time.
